[Bug 1411310] [NEW] [PATCH] Enable tuning of EXT images produced by lb_binary_rootfs

[Daniel Watkins]

Public bug reported:

We are currently moving to building CPC cloud images using Launchpad's
buildds.

A requirement for the CPC images is that (a) we produce EXT4 images with
4k blocks and, (b) that the images are resizable online to 2TB. The
attached debdiff provides config options which allow us to do just that
(from our custom livecd-rootfs).

It also applies the existing disk labelling option to disks produced in
lb_binary_rootfs.

** Affects: live-build (Ubuntu)
     Importance: Undecided
         Status: New

** Patch added: "ext-tuning.patch"
